If you have achieved this or any of the other Afterbirth achievements before the patch that added them in, you can unlock them by going to STATS and then SECRETS.

To get this achievement, you will need to get all 276 SECRETS, complete all 30 CHALLENGES, and pick up all 438 ITEMS. Many of the SECRETS are co-op baby unlocks, so you will have also have to get a full completion card on HARD with every character.

You will likely pick up the majority of items just trying to fill in all of your completion cards, but if you're like me and are missing one or two items at the end, there's a decent chance that they're Devil or Angel room items. The easiest way (at least for me) to grind those out was to play GREED mode as Isaac. Play every wave on every floor so you'll always get a Devil/Angel room and if you don't see the item you need, just roll your D6 and you get a second shot.

If you have any questions, let me know, and I'll happily try to help you out!
